Coolant treatment formulation
View Patent ↗A chemical formulation for treating coolant deficiencies, such as corrosion, scale, and low thermal transfer, and treating the root of most of the problems, which is water composition, and providing for preventative measures that further protect the systems that utilize the coolant. The formulation utilizes multiple ingredients, including an adsorbent, an emulsifier, a buffering agent, a dispersant, a deflocculate, a chelation agent, and a peptizing agent, each of which are chosen for a specific task and for the characteristics of having little or no impact on the environment, and for being either a food type additive, approved for use on food preparation surfaces, or otherwise generally recognized as safe. The ingredients, besides having their own specific task, when compounded with each other in the formulation or those elements found in the system being treated, also provide synergistic effects. All of these elements work together to produce a coolant treatment formulation that is safe to use, that is environmentally compatible, that is effective in both cleaning and protecting the treated system.
